Retro I got my pipes through Pud, the 750/4 Club 'Mr Fixit' in Yarram Victoria. They sound a bit like originals with the baffles removed, though it was 1974 when I last removed K2 baffles! They come painted or chromed depending on what you want - or, I had mine specially painted with a heat proof treatment in Castlemaine Vic where they do chrome look and paint for a lot of hotrod manifolds and pipes. From memory the set of four cost me around $900 AUS. Regards, Slug
